广州瑞欣铝石金复合板(隧道防火板)通常是指隧道混凝土结构进行防火保护的板材，其主要是由超高密度水泥纤维板双面复合经过铭化等处理的铝板后，再采用氟碳喷涂技术、聚酯辊涂技术加工形成。表面氟碳涂层具有卓越的抗腐蚀性和耐候性，能抗酸雨，盐雾和各种空气污染物，耐冷热性能极好，能抵御强烈素外线的照射，能长期保持不褪色，不粉化，使用寿命长。整体厚度10mmA級不燃，耐候性极高，抗冲击强度极强、安装施工便捷简单，未来势必成为主流影响行业方向。

Aluminum stone gold composite board (unne fire proof board) usually refiers to the board for fire protection of tunnel concrete structure. which is mainly formed by double-ided composite of ultra-high density cement fiber board ater chrome trealment, and then processed by fluorocarbon spraying technology and polyester roller coaling technology. fluorocarbon coating on the surface has exellent corrosion resistance and weather resistance, which can resist acid rain, salt fog and various air pollutants. Its excellnt cold and heat resistance can resist strong ultravlolet radlation, and maintaln color fastness, non-pulverizalion, long service life. With its overall thickness of 10mmA, non-combustible, high weather resistance. strong impact strength, and easy insallation and construction, it is bound to become the mainstream indusiry direction in the future.
